A method for making a device including a polyisobutylene-polyurethane block copolymer. The method includes polymerizing a polyisobutylene diol, a diisocyanate, and a chain extender within a solvent system to form a polyisobutylene-polyurethane block copolymer solution, depositing the polyisobutylene-polyurethane block copolymer solution onto at least a portion of the device, and evaporating the solvent system from the deposited polyisobutylene-polyurethane block copolymer solution. |
